RADIATION INDUCED POLMERIZATION OF SOME VINYL MONOMERS IN EMULSION SYSTEMS

摘要: Aqueous emulsions of styrene, methyl methacrylate, acrylate, and ethyl acrylate were polymerized with gamma radiation from a Co⁶⁰ source in the presence sodium dodecyl sulfate or laurate. The continuous measurement conversion reaction rate was carried out dilatometrically. acrylates fastest overall polymerization increased as follows: styrene < methacrylate acrylate. effects dose, temperature, original monomer emulsifier concentrations studied respect to following factors: properties polymer dispersions, number size particles, viscometrically determined molecular weights, monomer-water ratio, kinetic constants.
